SFI SYSTEM > CHECKING MONITOR STATUS |
for Preparation Click here
The purpose of the monitor result (mode 06) is to allow access to the results for on-board diagnostic monitoring tests of specific components/systems that are not continuously monitored. Examples are the catalyst and evaporative emission (EVAP) system.
The monitor result allows the OBD II scan tool to display the monitor status, test value, minimum test limit and maximum test limit. These data are displayed after the vehicle has been driven to run the monitor.
When the test value is not between the minimum and maximum test limits, the ECM (PCM) interprets this as a malfunction. When the component is not malfunctioning, if the difference between the test value and test limit is very small, the component will malfunction in the near future.
Perform the following procedure to view the monitor status. Although this procedure refers to the Lexus/Toyota diagnostic tester, the monitor status can be checked using a generic OBD II scan tool. Refer to the scan tool operator's manual for specific procedures.
| PERFORM MONITOR DRIVING PATTERN |
Connect the Techstream to the DLC3.
Turn the ignition switch to ON and turn the Techstream on.
Clear the DTCs (Click here).
Drive the vehicle in accordance with the applicable driving pattern described in Readiness Monitor Drive Pattern (Click here). Do not turn the ignition switch off.
- NOTICE:
- The test results will be lost if the ignition switch is turned off.
| ACCESS MONITOR RESULT |
Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor / Result.
Confirm the monitor status for each component.
- HINT:
- The monitor status for each component is displayed in the Result column.
- Pass: The component is functioning normally.
- Fail: The component is malfunctioning.
Display the test results and test value for a monitor by selecting the icon in the Details column for that monitor.
| CHECK COMPONENT STATUS |
Compare the test value with the minimum test limit (Min Limit) and maximum test limit (Max Limit).
If the test value is between the minimum and maximum test limits the component is functioning normally. If not, the component is malfunctioning. The test value is usually not near the test limits. If the test value is on the borderline of a test limit, the component will malfunction in the near future.
- HINT:
- The monitor result might on rare occasions be PASS (Pass) even if the malfunction indicator lamp (MIL) is illuminated. This indicates the system malfunctioned on a previous driving cycle. This might be caused by an intermittent problem.
